Seriously, the country is going to pass a law allowing gay marriage and outlaw
polygamy?

Try making it legal as right now if children are abused in
a regular home they are taken out. Making it legal would allow entities such as
child services to stop the 14 yr old bride business and the other exploitation
that goes on in communes.

There are economic and health benefits to
polygamy and even though it might not be the right thing to do it is like
selling cigarettes it is the best we can do with who we elected.

Legalizing their religious beliefs of polygamy will b=ring down their communes
faster than a bonfire. They will no longer be able to hide behind a national
ammendment allowing them to worship how they may. It allows the state to set
age and other legal limits and stop the ongoing issues that have plagued these
communes for decades.
